Application filed May 15, 1912. serial No. 697,366.

To all whom it may concern:

Be it known that I, DANIEL L. CHANDLER, a citizen of the United States,residing at Ayer, in the county of Middlesex and State of Massachusetts,have invented new and useful Improvements in Brush-Making 1 13- chines,of which the following is a specification.

This invention relates to brush making machines.

The object of the invention is to provide a machine by which bunches ofbristles may be selected from a mass of bristles and inserted in holdersto form-tufts and subsequently to force the holders containing saidbristles into a brush-stock which has previously been provided with therequired number of holes adapted to receive said bristle tufts.

In the attainment of the above object the bristles are selected in apredetermined quantity from the mass of bristles, doubled to form a loopand the loop inserted in one of said holes in said brush'stock, pushedthrough said stock and into the end of a tube which has previously beenchamfered and moved into alinement with the hole in said brush-stockthrough which said loop has been inserted. The tube is then compressedto bind said bristles therein and the portion thereof containing saidloop is cut oif and forced into the hole containing said tuft ofbristles.

The object is further to provide means adapted to hold and automaticallymove said brush-stock longitudinally and transversely to bring each ofthe holes therein into alinement with said tuft inserting means.

A further object is to provide means adapted to automaticallydiscontinue the operations of said machine upon the insert-ion of apredetermined number of tufts into abrush-stock.

A still further object is to provide means adapted to insure a perfectalinement of the tube and tube forcing means with their respectivecooperating mechanisms.

liith these ends in view, my invention con sists in certain features ofnovelty in the construction, combination and arrangement of parts bywhich the said objects and cer tain other objects hereinafter appearingare attained all as fully set forth in the following specification andparticularly pointed Referring to the drawings: Figure 1 is a plan Viewof a brush making mach ne embodying my invention.

Fig. 22 isa perspective view of one formof brush produced by the machine.

Like numerals refer to like partsthroughout the several views of thedrawings.

In the drawings 21 is a main driving shaft journaled in suitablebearings 22 and 23ona base or frame 24 and having a clutch pulley 25secured thereto adapted to beconnected to and disconnected from saiddriving shaft and indenting thev tube together 21 by the clutchactuating means hereinafter described. From the shaft 21 most of themechanisms of the machine receive their power.

Bristle feeding andtuft forming mechanism. (See Figs. 1, 7, 8 and l8.)Ahopper 26 for the bristles preferably consists of two walls 27 and 28provided, respectively, with grooves 29 and 30 constituting ways toreceive a weight 31 arranged to slide vertically therein and whichserves to crowd the bristles downwardly in said hopper, The hopper has aback wall 32 and the'mass of bristles is inserted in the hopper, asshownin Fig. 18, it being understood, however that when the hopper isloaded, it will be loaded with a greater mass of bristlesthan is shownin the drawings. A fourth wall 33 serves to confine the ends of thebristles at that side and is preferably removable in order to facilitatethe introduction of the mass of bristles. The hopper 26 which isotherwise open at the bottom is provided with two downwardly curveddepending guides 34 and 35 so shaped as to guide the bristles to thelowermost point thereof where they are to be engaged by the feedingdevices. The bottom of the weight 31 is preferably provided with aV-shaped notch 36 so' formed as to facilitate the crowding of thebristles toward the lowermost point of the guides 34' and 35.

The lowermost bristles of the mass in the hopper rest upon a bristlecarrier 37 in the manner shown in Figs. 7, 8 and 18. This bristlecarrier preferably consists of two plates 38 and 39 separated by a spacein which is located a plate 40, carrying at its upper portiona very thinplate or needle 41 provided at its forward end with a notch or recess"42' designed to engage the bristles "as they are crowded down into arecess or throat 43 provided in the upper side of the plates 38 and 39of the bristle carrier 37. Preferably, the size of this recess or throatis varied by-means of two adjustable plates 44 and 45, see Figs. 7 and8, secured to opposite sides of the bristle carrier 37. The bristlecarrier 37 is provided with a longitudinal passage 46, preferablycylin'drical in form, communicating with the recess or throat 43 andalso COIR- municating with a slot 47 in which the needle 41reciprocates, said needle also extending up into said cylindricalpassage, as clearly shown in Fig. 18.

The plates 38 and 39 which constitute the bristle. carrier 37 aresecured to a slide 48 mounted to slide on a suitable guide 49 providedon a bracket 50 mounted on the base of themachine. This-slide isreciprocated at the proper times in the operation of'the machine bya'cam 51 secured to the shaft 21 and having a groove 52 in which islocated a cam roll 53 j ournaledon the slide 48. The plate 40 is securedto a slide 54 mounted to slide suitable ways provided cated at theproper times in the operation of the machine by means of a cam 55secured to the shaft 21 and having a groove 56 in which is located a camroll 57 journaled on the slide 54.

In the operation of the bristle feeding and tuft forming mechanism, theneedle 41 is first advanced past the recess or throat 43 and in so doingsaid needle engages a number of bristles located in said recess, and inadvancing beyond said recess, said needle doubles the bristlestransversely thereof and forcesthem into the cylindrical passage 46,thus forming a tuft 0 having a loop (1 engaged by the needle. The tuftthus formed is carried forward to a point adjacent to the end or nose ofthe bristle carrier 37, said bristle carrier is then advanced to a pointadjacent to the holder into which the bristles are to be inserted, aswill appear more fully hereinafter, and then the needle 41 is advancedwithin the bristle carrier to carry the tuft out of the bristle carrierinto the bristle holder.

Tube feeding mechanism. (See Figs. 1, 2, 3, 10 and 14.)A suitablemetallic tube 58 passes between a pair of feed rolls 59 and 60 securedto shafts 61 and 62, respectively, the latter shaft being journaled insuitable bearings 63 and 64 provided on a slide 65 mounted to slidetransversely of the longitudinal dimension of the tube 58 in, ways 66provided on a bracket 67 secured 'to the base 24. The shaft 61 isjournaled in bearings 68 and 69 mounted to slide vertically in ways 70and 71 provided on the slide 65. Suitable compression springs 72 and 73provided with adjusting screws 74 and 75, respectively, urge thebearings 68 and 69 downwardly, thus causing the feed roll 59 to pressthe tube 58 against the feed roll 60 and assuring sufficient frictionalengagement so that the tube may be properly fed when the shafts 61 and62 are rotated. The shafts 61 and 62 are preferably geared together bygears 76 and 77 secured to said shafts, respectively, and meshing witheach other, thus causing said shafts to be rotated in unison and thefeed rolls 59 and 60 to be positively rotated at the same speed.

At the proper times in the operation of the machine, the feed rolls 59and 60 are rotated to intermittently feed the tube 58 longitudinally bysuitable mechanism. Preferably, this mechanism comprises a ratchet 78having a hub 7 9 journaled in a suitable bearing provided in a bracket.80 and'held against longitudinal movement therein by a collar 81secured to said hub. The ratchet 78 is provided at its opposite sidewith a hub 82 upon which a pawl carrying lever 83 is mounted to rock andis held against longitudinal movement by a collar 84 secured to saidhub.

- said ratchet prevents i The slide is reciprocated by l\'founted uponthe pawl carrier 83 is a feed pawl 85 engaging the teeth of the ratchet78, see particularly Figs. 1 and 3,

arranged to drive said ratchet in one direction, while a stop pawl 86,see Figs. 1 and 10,-pivoted upon. the bracket 80 engaging a reverserotation thereof. The pawl carrier 83 is rocked at the proper times inthe operation'of the machine by a slide 87, see Figs. 1 and 3, connectedat its forward end to said pawl carrierby'a pivot 88 and having its rearend mounted to slide in a suitable guide 89.

a cam 90 having a groove 91 in which is located a cam roll 92 journaledon said slide.

- At certain times in the-operation of the machine, the tube is movedfrom right to left, Fig. 1, in order to present the end of thetubefir'st to the action of a bur-removing or chamfering means and thento the action ofdies for compressing the walls of the tube, as willappearhereinafter. In order that the tube may be properly guided andheld at that end .which is to he instrumentalities, there is provided aguide 93, (see particularly Fig. 1,) secured to the slide It will beevident that since the slide 05 is to be moved to carry the feed rollsand 0 to and fro from right to left and vice versa, there must beprovided a sliding connection operated upon by these between the shaft62 and the ratchet 78 and to this end said ratchet is provided with afeather 9% arranged to slide in the ke'y way 95 provided in said shaft.

Theslide 65 is reciprocated by mechanism preferably comprising a link 96pivotally connected at one end to said slide and at its other end to therocker arm 01 see Fig. 2, secured to a rock shaft- 98. This rock shaft,whichis jo'urnaled in suitable bearings 99 on the base 24:.

is rocked at the the operation of the ma- 100 secured to the shaft 21101 in which is located a on an arm 103 es proper times in chine by acam having a groove cam roll 102 journalcd "cured to said rock shaft.

Tube cha'nzfering or bur-rmwvz'ng mechanism. (See Figs. 1, 3 and 18.)Inorder that the bur may be removed from the previously cut end of thetube 58 there is provided a suitable rotating chamfering tool 104:suitably shaped to bevel or chamfer. the inside of the end of the tube.This tool is suitably mounted or secured in the end of a shaft 105journal ed insuitablebearings tube,'by means of a cam 106 and 107 on aslide 108 mounted to slide 'on suitable ways 109 on the bracket 50, see

Fig. 18. tion 'of the machine, the slide 108 is car'ied forward and backto carry the cha ifering t-ool toward and away from the end secured tothe shaft-21 and having a groove 111.in which At the proper tune iii theopera-- of the is located a cam roll 112' journaledon said slide. Theshaft 105 is rotated by'meansof a belt passing around a pulley 113secured to said shaft. 1

Tub com-pressing and indenting mechanism... (See Figs. 1,2,17.)-,'Afterthe bur has been removed from the end of the tube bychamfering thesame, as hereinbefore described, the tube is carried fromthe position shown in Fig. 1 towardthe left, a longitudinal feedingmovement is imparted thereto to bring the same into the position shownin Fig. 15. and the tuft is then inserted intothe 'hamfered end of thetube in the manner shown in said figure by advancing the needle 11 intothe position shown, into the tube. After this has taken place,'the endof the tube con taining the tuft of bristles is compressed and indentedby the following mechanism. Referring now to Fig. 5, it will be observedthatgrouped about the end of the tube 58 there is a plurality of diesfor accomplishing the compressing and indenting of the tube. these diesbeing preferably four in number arranged in pairs, one pair consistingof the members 114 and 115 and the other pair consisting of the members116 and 117, all of which are mounted to slide radially in a circulardie holder or support 118 and are given saidsliding movementby means ofa rin 1119 swivelcd upon said die holder. This ring carries a pluralityof arms 120, 121, 122, and and pivoted to the outer ends of thedies'114, 115,116, and 117, respectively. shown in Fig. 5. As

- this ringis rocked to and fro on the stationary die holder 118 by amechanism which will be described hereinafter, the swinging arms justdescribed act to impart to their respective dies a simultaneous movementtoward the tube and away from the tube The extremities of the dies wherthey engage the tube are substantially cylindrically formed. Preferablythe die members 110 and 117 are provided. respectively. with spurs 124'.and 1'25 which indent the tube and form indentations andl'QT extendinginto the loop of the tuft in the manner illustrated in Fig; 22. thuslocking the tuft within the tube. Itis also highly desirable that theholder shall be compressed around that portion which is located betweenthe indentations and 12? and the end of the tubefrom which the bristlesproject and to this end the die members 114-. 115, 116 and 117 areprovided, more or less abruptshoulders 128.. 120. and 131. asbestillustrated in 1 s. 15. .16 and'17,these shouldered portions of the diesserving to form a reduced portion or necl: 132 firmlygrippingthebristles adjacent to that end of the holder or tubefroinwhich they project. compressing respectivc y, with.

This the entire operation of 5, 1i, 1c and ing the same issimultaneously accomplished by the simultaneous action of all four ofthe die members.

The die actuating ring 119 is rocked to and fro by any suitable meansand for this purpose I preferably provide said ring with a dependingarm. 133 connected by a link 134 to a rocker arm 135 secured to a rockshaft 4 136 j ournaled in bearings 137 on the base 24.

A rocking motion is imparted to the rock shaft 136 by means of a cam 138secured to the shaft 21 and having a groove 139 in which is located acam roll 140 journaled on an arm 141 secured to said rock shaft.

Tube cutting 07? mechanism. (See Figs. 1, 2 and 14.)After the bristleshave been inserted in the end of the tube and the end of the tube hasbeen compressed and indented, as just described, that portion of thetube which contains the bristles is out off of the remainder of the tubeby suitable means preferably consisting of a circular saw 142 which isplaced adjacent to the front face of the dies and the die holder.

- This saw is secured to the shaft 143 journaled in a suitable bearingprovided in a rocker arm 144 secured to a rock shaft 145 mounted insuitable bearings 146 on the base 24. The shaft 143 has secured theretoa spur gear 147 meshing into an intermediate gear 148 rotatably mountedupon the arm 144, said gear in turn meshing with a gear 149 secured to ashaft 150 also journaled in the rocker arm 144 and having securedthereto a pulley 151 driven by a belt 152 from overhead. The saw iscarried to and fro across the path of the tube 58 at the proper times inthe operation of the machine by a cam 153 secured to the shaft 21 andhaving a groove 154 in which is located a cam roll 155 journaled on anarm 156 secured to the rock shaft 145.

By the mechanism just described, the tube is severed, thus leavin aportion thereof forming a holder in which the bristles are firmlysecured, the remainder of the tube being returned to its initialposition to be operated upon by the bur-removing or chamfering mechanismwhile said out off portion or holder is acted upon by mechanismhereinafter described.

Brush-stool: holder and actuating mechanism there/"07. (See Figs. 1, 2,3, 4, 9 and 14, referring particularly to Figs. 4 and 14.)The circulardie holder or support 118 which is secured or supported upon the bracket50 has extending horizontally therethrough a recess or rectangular slot157 and in which is mounted a brush-stock holder, preferably consistingof a slide 158 having a slot 159 extending longitudinally of said slide158, and provided-with grooves 160 upon opposite sides of said slot saidgrooves 160 being. formed preferably to correspond with the oppositeedges of 9.

brush-stock 161 substantially equal in length to the body portion 162 ofsaid brush-stock. The slot 159 extends longitudinally of the slide 158terminating at 163, said terminating point thereof being preferably atone side of a point on said slide through which the axis of thecylindrical die 118 passes while said slot 159 extends to the end ofsaid slide 158 upon the opposite side of said point from that upon whichthe end 163 is located, thus permitting the brush-stock 161 to beinserted into said slot between the grooves 160 against the end 163 ofsaid slot, the slide 158 being but slightly thicker than the brush-stock161. The slot 159 is made long for the purpose of receiving abrush-stock having a handle attached thereto as illustrated in Fig. 19and a clamping slide 164 provided with a recess 165 which is adapted toreceive the end of said handle and center the same in said slot 159relatively to the body 162 of said brush-stock. The slide 164 isprovided with tongues 166 which extend longitudinally thereof for aportion of its length which engage and are guided by grooves 167 formedin opposite walls of said slot 159. A thumb screw 168 has screw-threadedengagement with said slide and is adapted to engage a cross piece 169which connects the outer ends of the slide 158 to prevent spreadingthereof, said" screw 168 being for the purpose of clamping said slidewithin said groove to secure sitid brush-stock against the end 163 ofsaid s ot.

When it is desired to hold a brush-stock of the character illustrated inFig. 20, a filler 170 is employed having a tapped hole 171 adapted toreceive the screw-threaded I end 172 of said brush-stock, said fillerbeing substantially equal in length to the handle of the brush-stockillustrated in Fig. 19. The slide 158 which constitutes the holder forsaid brush-stock is mounted for a longitudinal sliding movement in aholder slide 173, the opposite faces of which bear against oppositefaces of the rectangular slot 157, provision being made in said slot topermit of a substantial movement of said slide 173 transversely of saidslide 158, said slide 173 being guided in said transverse movement bypins 174 and 17 5 upon opposite edges of said slide respectively whichmove in guides 176 and 177 respectively in said cylindrical holder,suitable clearance being provided in the ring 119 to permit the same tobe rocked without interfering with saidslide 173 or said pin 17 5.

By reference to Fig. 14 it will be seen that the slide 158 is arrangedat one side of the center of the holder slide 173, thus bringagainst thepartition 180 of said cylindrical holder. Said partition 180 ispreferably holder I 158 in close very thin and not only constitutes aguide for said slides but the opposite face thereof constitutes a guidefor the dies 114, 115, 116 and 117. A cylindrical hole or guideway 181is provided in said partition concentric with the axis of saidcylindrical die. and of suliicientsize to admit the end of the tube 58.It will also be seen by reference to said Fig. 1=1 that the body portion162 of the brush-stock 161 is held within the proximity to said hole181.

- The form of brush-stock illustrated in Figs. 19 andhiO is providedwith a plurality of'series of holes 182 preferably arranged parallelwith each other and so arranged in said holder that one of said holes182 will be in alinement with the center of said hole 181, the hole a"in Fig. at being 111 alinement therewith in the present instance. Tinslide 158 is moved longitudinally .inthe slide holder 173 to bring theholes 182 successively into alinement with the hole 181 at the propertimes in the operation of the machine by a cam 188 having a cam groove18% in 'hichis located a cam roll 185 pivotally mountedupon a cam slide186 adapted to slide in a guide 187 and pivotally connected to the slide158, which for the purpose of adjustment and to properly aline holes inbrush-stocks of various sizes with the hole 181 is providedwith anadjustable connection 188.

A transverse movement is imparted to the holder slide 173 andconsequently to the brush-stock 161 to bring the several parallel seriesof holes successively into alinement ith the center of the hole 181 atthe proper times in the operation of the machine. by a cam 189 having acam groove 190 in which is located a cam roll 191 pivoted upon the endof a lever 192, the lever 192 being pivoted at 193 in bracket 194secured to the base 2-1, said lever.192 being pivotally connected at 195to the pin 175 by an adjustable link 196.

. The cams 183 and 189 are secured to the end of-a shaft 197 journa-ledin'bearings 198 on the base 2%, said shaft having a suitableintermittent rotary motion imparted thereto by suitable mechanismpreferably consisting of a pawl and ratchet feed mechanism 199, seeFigs. 1 and 9, said mechanism nsisting of a ratchet disk 200 provided'Witil teeth 201 adapted to be engaged by a pawl 202 pivotally mountedupon the end of a rocker ar1n203,: said rocker arm being pivotallymounted upon the-shaft 197 inside of said disk 200. said disk being ofsaidshaft in order that it. may be easily removed when it is desired toreplace the sameby a disk having a greater or less number of teeththere-on. A rocking movement imparted to the rocker arm Q08to feed saidratchet disk by a rod 904 slidably located at the end &

mounted in a bearing or guide. 205 upon the stationary bracket 50, saidrod being engaged by a cam 206 which is secured upon the slide 48,,operated as hereinbefore described, to move the bristle carrier 87. Thus,it will be seen that for each movement of said bristle carrier to form atuft of bristles said disk 200 will be rotated one tooth thereby rockingthe shaft 197 and consequently moving the slide 158 longitudinally adistance equivalent to the distance between the centers of twosuccessive holes. As the slide 48 recedes withdrawing the cam 206 fromthe end of the rod 204, a spring initial positions to engage another ofthe teeth 201; said disk 200 is prevented from being rotated in areverse direction during the return movement of the pawl 202 by a stoppawl 208. To insure the stopping of said ratchet disk 200 at thecompletion of the movement of the rocker arm 208 and to check themovement of said brush-stock I have provided a frictional device 209secured to one of the bearing brackets 198 and adapted to engage oneface of said disk 200, said frictional device being shown in section inFig. 21.

It will be observed by referring to Figs. 19 and 20 that eachbrush-stock shown in said figures is provided with thirty-one holesarranged in three parallel series. Assuming that the brush is located inthe same relation to the hole 181 as that shown in Fig 4: the mechanismwhich feeds said bXUFlr stock must be arranged to feed the samelongitudinally step by step until each hole in the series of holes inwhich the hole a is located has been acted upon, as will be hereinafterdescribed, whereupon said brush is moved transversely to bring thesecond of said series of holes into alinement with the hole 181. Saidbrush must then be moved longitudinally thereof until each of theseholes has been acted upon when the final series of holes will be broughtinto alinement with said hole 181 as have been the two other series ofholes, and at the completion of said last series of holes the machinewill be stopped as hereinafter described.

When it is desired to insert bristles in brush-stocks of a differentdesign and with a different number of holes therein a holder of asuitable size is provided and inserted in place of the holder 158 andthe cams 188 and 189 and disk, 200 are all replaced by cams of theproper design and a disk with the proper number of teeth .thereon,different sizes of which are held in readiness to be used for thedifferent size brush-stocks into which it is desiredto insert bristles,itbeing understood that the cam 206 has a suiiicient throw toaccommodate the different throw .cquired.

207 returns the rocker arm 208 and the pawl 202 to their Figs. 1, 2, 3,14, 15, 16 and 17, particularly Figs. 1, 2 and 14.)F.ollowing thechamfering oft-he tube 58, as hereinbefore described, said tube is fedfrom the tube chamfering means by the movement of the slide 65. towardthe :left in Fig. 1 and the end of said tube is presented to thebrush-stock 161 between the-dies 114, 115, 116 and 117 up to and intoalinement with the hole 181. The needle 41 is then advanced within thebristle carrier 37 and the loop (2 of the bunch of bristles carriedthereby is inserted through the hole a and into the end of said tube 58after which said needle is withdrawn and the compressing dies 114, 115,116 and 117 are actuated to compress the end of said tube against saidbristles, as hereinbefore described. Y The saw 142 is then brought intoaction to cut off the end of said tube containing said bristles afterwhich it recedes to the position illustrated in Fig. 14 and the dies114, 115, 116 and 117 are withdrawn to the positions shown in Fig. 5,thus leaving said tuft supported within the hole a in readiness for theholder 212 to beforced into said hole.

It, will be observed that the holes 182 are tapered or in other wordsthe ends of the holes into which the tufts of bristles are inserted aresmaller in diameter than at the opposite end of said holes or at theside of said brush-stock upon which said holder 212 is compressed. Itwill also be noted that holder after said holder has been compressed.

Secured to the slide is a bracket 213 having a guide 214 adapted toguide a driver bar 215, said driver bar having a reduced end 216preferably of the same diameter as the tube 58. A rod 217 is slidablyarranged in guides 218 formed in said bracket 213, and adapted to imparta reciprocatory motion to said driver bar 215 through the arm 219. Saidrod 217 is adapted to be actuated to move said driver bar toward saidbrushstock by an arm or actuator 220 secured upon a rock shaft 221journaled in bearings 222 in the base 24, while a movement of saiddriver bar away from said brush-stock is imparted thereto by av spring223 engaging at one of its ends one of the guides 218 and at itsopposite end a collar 224 which is secured to said rod 217.

The driver bar 215 as illustrated in Figs. 1 and 14 is in alinement withthe hole 181 and the tuft feeding needle 41 and at the proper times inthe operation of the machine said driver bar is reciprocated in theguide 214 and engages the end of the cut off portion 212 of said tubeand forces the same through the guideway 181 and into the hole in whichthe tuft of bristles within said holder is located, by suitable meanspreferably consisting ef 'a cam 225, see Fig. 1, having a cam groove 226in which is located a cam roll 227 journaled to rotate upon the end of aslide 228, said slide being arranged to slide in a' guide 229 adjacentto said cam and connected at its opposite end to a rocker arm 230 fastupon said rockshaft 221. As hereinbefore stated the bracket supportingsaid driver bar is mounted upon the slide 65 and as said slide 65 ismoved from left to right, Fig. 1, to present the tube 58 first to thechamfering tool 104 and then between the compressing dies or intoalinement with the bristle tuft forming means, said driver bar 215 willbe moved from'its position shown in Fig. 1 to the left and out of rangewith the actuator 220, or in other words, said tube feeding means andsaid tube forcing means will be alternately moved into alinement with,the holes 181 or with the axis of the cylindrical support 118. The endof the rod 217 is preferably provided with an adjusting means comprisinga screw 231 having screwthreaded engagement with the end of said rod andthe check nut 232, the head of said screw 231 being arranged to beengaged by the upper end of the rocker arm 220 when said driver bar isin alinement with the hole 181. The collar 224 is provided with anextension having a lug 233 adapted to be engaged by the upper end'of therocker arm 220 to insure the returnof said driver bar to its outerposition, upon the completion of its holder inserting movement, in casethe spring 223 fails to work.

To insure a proper or perfect alinement between the driver bar 215 andthe hole 181 and the tube 58 and its chamfering tool 104, a rocker arm234 is provided which is secured to the shaft 221 and has at its upperend a tongue 235-which alines with a com plementary slot 236 formed in aplate 237 secured to the slide 65, the corners of said plate beingslightly beveled at the opposite sides of said slot to insure theentrance of said tongue therein. A second .slot 238 is provided in saidplate 237 and upon the movement of the slide 65 to the left. to bringthe tube 58 into alinement with said tube inserting means said slot 238will be brought into alinement-with the tongue 235 and upon the rockingof the shaft 221 said tongue will enter one or the other of said slotsand if there happens to be any wear between the cam groove and the camroll, or the connections between said slide 65 and said actuating meansand said means fail to properly center or aline said severalinstrumentalities, the movements of said slide will be completed y theengagement of said tongue with said slots.

Stop mechanism. 13.)In a machine of this character it is essential thatupon the completion of the bristle tuft inserting'operations and after(See Figs; 1, 9, 12 and I all the holes in said brush-stock have beenthe following mechanism is preferably employed.-"*Theclutch pulley 25.is rotatably mounted upon the shaft 21 and has secured to'githe hubthereof aratchet 239 which rot tes against a disk 240 while said pulleyis retained on said shaft bya collar 241. The disk 240 is secured to thedriving shaft 21 and has pivotally mounted at 242 a lever .243 having atooth 244 adapted to engage the teeth -of the ratchet 239, said toothbeing normally retained in engagement with. said ratchet by a spring245, see particularly Figs. 2, 12 and 13. The opposite end of the lever243 from that upon which the tooth 24 4 lislocated is adapted to beengaged by fai projection on a bell crank lever 246 pivote'di 'at- 247to a portion of the frame, said lever 246 being held'in its normalposition, as illustrated in Fig. 13, and against a stop 248 by a spring249 engaging a pin 250. It will be seen by reference to this figure thatthe tooth 244 is out of engagement with the teeth 239 with the oppositeend of the lever 243 engaging a projection on the lever 246 and alsoengaging a stop pin 251 on the disk 240. Thus it will be seen that saiddisk and shaft 21.are prevented from rotating while the ratchet 239 ispermitted to rotate fr'eely upon said shaft. hen it is desired toconnect said shaft with said pulley 25 to start the machine intooperation, the bell crank lever 246 is moved in the direction of thearrow b by any suitable means, preferably by the depressing of thetreadle rod 252, whereupon the lever 243 will be released and the spring2451 will force the tooth 244 into engagement with the teeth" upon theratchet 239, thus causing the shaft 21 to be rotated until said teethhave been again disconnected.

Upon the movement of the lever 246 in the direction of the arrow b thepin 250 will be moved to the right in Figs. 12 and 13 slightlydepressing the toothed end 253 of a lever 254 secured to the rock shaft255 journaled in bearings 256m the base 24. As said. pin 250 is advancedbeyond the tooth 253, the spring 257 returns said lever 254 and tooth253 to its normalposition whereupon said pin will engage said tooth uponthe release of said treadle rod 252 and withhold the projection on thelever 246 from entering the path of the outer end of the le-' ver 243,thus permitting the tooth 244 to remain in engagement with the ratchet239. The rock shaft 255 has upon its opposite end a rocker arm 258, seeFigs. 9 and 11,

havingat its upper, end an inclined tooth. 259 which is adapted to beengaged when is desired'to stop themachine, by projec-"j tions 260suitably arranged upon one face cf the ratchet disk 200- and by reasonof said path of the outer end'of the lever cause said lever to be rockedupon its pivot tuft and stock occupied by said bristles. beingshouldered to conform wit engagement the lever 258 is ;1-deked-,-.thereby rocking-the shaft 255 andthe'lver- 254 to release the pin 250,thus permitting the pro jection on the lever 246 to move into t e 243and 242 until said lever engages the stop pin-251',

thereby disconnecting the shaft 21 from its driving pulley andeftectually stopping the rotation of said shaft.

It'will be'noted that in Fig. 9 the disk 200 is provided with twoprojections 260, thus the machine will be automatically stopped twiceduringv one rotation of said disk, consequently two brush-stocks areadapted to be filled withtufts of bristles during said rotation. It willalso be obvious that by rearranging the teeth upon the ratchet disk 200and the cam grooves in the cams 183 and 189 to correspond with therearrangement of said teeth that a greater or less number of said stops260 may be em ployed upon the face of said disk to be acted upon duringone rotation thereof.-

The general operation of the machine hereinbefore described is asfollows: The tube is first presented to the action of the bur-removingvor chamfering mechanism. The inside of the end of the tube is cham--fered the tube is then carried into a position between the dies andinto alinement with the hole 181, one of the holes in the brush-stockand also into alinment with the tuftinserting mechanism. A set ofbristles is then taken from the mass in the hopper and bent transverselyto form a tuft hav-.

ing a loop, by the cociperative action ofthe needle and bristle carrier.The bristle carrier is then advanced to a point adjacent to saidbrush-stock, as shown in Figs. 15 and 16. The needle is then advanced insaid bristle carrier and inserts the, looped end of the tuft through thehole in saidbrush-stock and into the chamfered end of the tube, thebristles at this time remaining in the hole in said brush-stock. Thetube compressing dies are now brought into action and the tubecompressed to bind the bristles therein and while said dies are"engaging said tube the same is out off from the remainder of the tubeadjacent to said loop. The dies are then retracted releasing thefinished tuft which is supported in the hole in the stock. The tubefeeding means is returned to its alinement with the chamfering mechanismand by said movement a driver bar is brought into alinement with, saidfinished the hole in which it-is located and forces said holder into thehole in s id-brush- (1- hole of said compressing holder. nTh

is the "retracted to the posi nf s n I tl lly isu'ccessive brushholetherein into alinement with the tuft inserting mechanism and the partsare in positlon to duplicate the operation ]USt described. At theconclusion of apredetermined number of insertions of bristle tufts inthe brush-stock, as just described, the machine is automaticallystopped. the brushstock removed and a new one placed therein inreadiness to be operated upon.

From the foregoing description, it will be seen that simple andeiiicient means are provided for accomplishing the objects of theinvention, but while the elements herein shown and described are welladapted to serve the' functions set forth, it is obvious that variousminor changes may be made in the proportions, shape and arrangement ofthe several parts without departing from the spirit and scope of theinvention as defined in the appended claims.
